Abstract
The utility model provides an American ring main unit with an insulation protective cover. The American ring main unit includes a body. The interior of the body is divided into a plurality of accommodating spaces. Wire inlet and outlet sleeves are disposed on an outer side wall of the body. Insulating protective covers are disposed outside the wire inlet and outlet sleeves. Upper and lower ends of the insulating protective covers are provided with openings, and the other portions of the insulating protective covers are sealed. Each circuit is isolated by the insulating protective covers and covered in a separate space. When a circuit needs hot-line operation or maintenance, on-site installation and maintenance staff simply need to remove the protective cover of the circuit so as to avoid mistakenly touching other adjacent hot-line circuits, thereby effectively reducing the safety risks and preventing accidental electrocution. Meanwhile, since the upper and lower ends of the insulating protective cover are provided with openings, the water vapor entering from a cable duct through the bottom of an outer box flows and diffuses up and down via the openings to prevent condensation of the water vapor in the wire inlet and outlet sleeves on the side wall of the body so that the insulation performance is affected and safety risks are avoided.
